GEORGE BOALEY STOCK, OF PORT HURON, MICHIGAN.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 791,054, dated May 30, 1905.

Application filed September 23,1904. Serial No. 225,667.

To all whom, it may concern:

Be it known that I, GEORGE BOALEY Srocx, a citizen of the United States of America, residing at Port Huron, in the county of St. Clair and State of Michigan, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

This invention relates to journal-boxes, and more especially to that kind which are so applied to a bearing as to be yieldable.

An object of the invention is to produce a box to receive absorbent material adapted to be saturated with a lubricant, the box being sectional in order that it may be easily applied to a journal or conveniently removed therefrom.

The invention applies to that class which employs a spring to support or hold the box in operative position; and a further object of the invention is to produce novel means whereby the spring may be detachably secured to the box.

Another object of the invention is to produce a device of this character that will be simple in construction, efficient in practice, and economical in manufacture.

With the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and claimed.

In describing the invention in detail reference will be had to the accompanying drawings, forming part of this specification,wherein like characters denote corresponding parts in the several views, and in which Figure 1 is a view in perspective of the journal-box embodying my invention, the spring for securing the same being omitted. Fig. 2 is a fragmentary view in perspective of engaging corners of the box, the same being shown in a position ready to be attached. Fig. 3 is a sectional view of the invention in applied position, and Figs. 4 and 5 are views of a modified form of the invention.

-In the drawings, 1 1 and 2 2 indicate the sections of a journal-box, and 3 the cover therefor hinged to the top of one of the sections 1 at 1. Thelower edge of the sections 2 2 are provided with the curved cut-away portion 5, adapted to conform to the contour of the journal to which it is applied. Formed integral with and at right angles to the sections, at the sides thereof, are plates 6 and 7, said plates being from end to end approximately midway the sections. The plates are provided with the angular notches 8, the notches on the plates 6 being opposite those on the plates 7 These plates, by means of the notches, are adapted to interlock, and thereby removably secure the sections in position.

Centrally of the sections 1 1 are apertures 9, having the upwardly extending lug 10 therein. This lug is adapted to receive a loop or curved end 11 of a spiral spring 12, the opposite end of said spring being suitably secured to a bearing or support 18, as at 15. The springs 12 are exterior of the box, and therefore readily accessible for removal or application. The springs 12 not only hold the box against its support, but hold the sections of the box from disengagement one from the other, as readily seen in Figs. 1 and 3 of the drawings.

Although not shown, the box is adapted to be filled with an absorbent material saturated with a lubricant, the said absorbent material protecting the surface of the journal 16 from accumulation of dust and other foreign substances, which would impair the bearing-surface of said journal. The springs 12, being anchored at one end to the journal-support, draw the box against the receptacle, yet at the same time permit of a slight movement of the box, the advantages of which are obvious.

In Figs. 4: and 5 is shown a box of similar construction, except that the box is made solid and is not formed of separable sections, as shown in the other figures. A further difference in this form over that heretofore described is that the apertures in the sides are omitted, and the said sides are provided with integral ribs 17, which ribs terminate at the upper ends in spurs 18. The application of this form is the same as the first-described device, with the upper ends of the springs 19 removably engaging the spurs 18 of the ribs 17.

The construction and advantages of the invention will, it is thought, be fully understood from the foregoing.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with a journal-bearing, a box adapted to bear thereagainst, said box being formed in sections, there being plates on the sections adapted to interlock, and means exterior of the box for securing the box against the shaft.

2. In combination with a journal-support,

a box adapted to bear against the journal, said:

box being formed in sections, there being plates formed at the sides of the sections and atright angles thereto, said plates being ad apted to interlap, and means exterior of the box fior holding the box against the journal.

3. In combination with a journal-support,

a box adapted to bear against the journal, said box being formed in sections, and there being plates formed approximately centrally of the sections, said plates being adapted to interlap, and means exterior of the box for hold-
